Hey, thanks for sendin your question today :)

Let's solve -7+2w=-1!

Simplify both sides of the equation  

2w−7=−1

Add 7 to both sides.

2w−7+7=−1+7

Simplify.

2w=6

Divide both sides by 2.

w = 3

Glad we would work together today :)

A cylinder with 1/4 of a section removed has a radius of 4 cm for the base and a height of 10 cm.
Advocard [28]

Answer:

Volume of the solid is 377 cm³.

Step-by-step explanation:

Volume of the cylinder = \pi r^{2}h

Here, r = radius of the cylinder

h = Height of the cylinder

By substituting the values in the formula, (r = 4 cm and h = 10 cm)

Volume of the cylinder = \pi (4)^2(10)

                                      = 160π

Since one fourth of the cylinder is removed,

Volume of the remaining cylinder = 160π - \frac{160\pi }{4}

                                                        = 160π - 40π

                                                        = 120π

                                                        = 120(3.14)

                                                        = 376.8 cm³

                                                        ≈ 377 cm³

Volume of the solid is 377 cm³.
